SHUTTER-FASTENER. I l

I Applloation filed July 17,1905. Serial No. 270,085- I further object being to construct a fastener in which the number'of loose detached parts is reduced to a minimum, thus avoiding loss of :the waste of time in placing the fastenings in po sition.

With these and other objects in view, as will more fully hereinafter appear, the invena tion consists in certain novel featuresof construction and arran comp anying drawings ,and particularly point ed out in the appended claims, it bein understood that various changes in the orm,

proportions, size, andminor details of the structure may be made without departing from the spirit or sacrificing any. of the ad' vantages 0 the invention.

In the accompanying drawings, Fi ure 1 is I a sectional plan v1ew of a shutteras'tener constructed in accordance with the invention. Fig. 2 is a front elevation of the same. Figs. 3, 4, 5, and 6 are detail sectional views illustrating modified forms of fastenirgs, more particularly referred to hereina ter.

the several figures of the drawings.

Thefastener comprises in general a latch member 10, that is pivotally mounted on a stud member 11 and is provided with a slot for engagement with a second stud orkeeper member 12, the two studs being secured to the members to be fastened. together. The

opposite end with a' slot or recess for the reception of a stud member, and with this class of latch many different forms of pivot and keeper studs can be employed, these in Specification of Letters Patent.

most'cases being in the form of grooved cire cularblocks having central openings forthe passage ofnails, screws, or similar securing devices; but in all the'sefastenings thepar-ts are separate, each complete fastening con stituting five or six members which are usually detached from eachbther, requiring con siderable time in sorting andin assembling the parts preliminary to placing them in position, while in many cases parts are lost or mislaid and must be separately ordered, resulting in considerable loss and annoyance. In carrying out my invention fastening is so made that each consists of but two arts,

andthese being furnished withattache fastening devices may be readily secured in place-without loss of time. o

Each of the membersshown in Figs. 11 comprises a disk 15, provided with a cylindrical stud 16, having an internally+threaded open- 3 ing for thereception of a screw 17;, the screw ement, of parts, hereinafter fully describe illustrated in the achaving an enlarged head 18, which serves to prevent displacement of thellatch 10 from the stud; The screw is provided with two threaded portions 18 and 19 of diflerent" di ameter, respectively, the portion 18 entering the threaded opening in the stud 16, whilethe reduced portion 19 is arranged to screw into a shutter 01' otherarticle to be fastened. In assembling the parts at the factory. the opening in the latch 10 is placed over one of the studs, and then the screw is inserted and turned in order to confine the latch in osition. The other member is completed by simply placing a screw within the stud, and the article when finished therefore comprises two detached members which may be readily placed in position by inserting a screw-driver in a slotted head of the, screw or by driving the screw in by a hammer or other tool. is 'found'that by assembling the parts in this .manner the fastenings may be placed in position with less time and effort than where all I v of theparts are separateand must be assembled by the workman. At the same time the turning of the screw and securing the same in "the wood will also insure the turning home of the threaded portion 18, and the two screw members will serve each as a lock for pre venting rotative movement of the other, so

that the parts are more 'firmly held in position than is the casein fastenings of the ordinary yp o In Fig. 3 is illustrated asli ht modification of the invention, wherein t e screw 17* is of uniform diameter throughout its entire length and the threaded opening in the stud is of the same diameter as that formed in the wood by the passage of the screw.

Fig. 4. illustrates a further modification in which the screw 17 is in the form of an ordinary wood-screw. In this case the disk and stud 16* remain the same, while the head of the screw enters an opening in a disk 18*, which performs the same function as the enlarged. head of the screw previously described.

In Fig. 5 is illustrated a modification of the invention suitable only for the keeper-studs. In this case the screw enters a threaded opening in a stud member 16*, having integral flanges or disks 15 and 18*.

In Fig. 6 a further modification is illustrated. In this case the stud member 16 is formed integral with the outer flange 18 and thcinner flange 15 is threaded for the passage of the screw 17 In this case the screw is a separate member and may be passed through an unthreaded opening in the stud 16 and thence through a threaded opening formed in the inner flange 15 With a device constructed in accordance with this invention there is no danger of loss of parts due to carelessness in packing and no waste of time in sorting and selecting the various members necessary to constitute a complete fastening.

Havin thus described the invention, what is claime is- 1. In a latch-fastener for shutters and the like, a disk having a centrally-dis osed stud projecting from one face thereo' and provided with a smooth circular outer face, and with a centrally-disposed threaded opening that extends, also, through the disk, a screw having a threaded portion extending through said opening and arranged to enter the material to which said fastening is to be secured, the screw having an enlarged head which abuts against the outer end of the stud.

2. In a latch-fastening for shutters and the like, a disk provided with a centrally-disposed stud having a smooth circular periphery and provided with a centrally-disposed threaded opening, a screw having a threaded portion extending through said opening and provided with an enlar ed head that abuts against the outer end 0 the stud, that portion of the screw extending beyond the disk being reduced in diameter and provided with threads for engaging the material to which the fastening is to be secured.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
